Abstract

PURPOSE:To call an opposite subscriber from any telephone set only by remembering an abbreviated dial number by constituting an electronic exchange so that the opposite subscriber corresponding to the abbreviated dial number is called by calling a specific line wire and dialing the abbreviated dial number. CONSTITUTION:In detecting an incoming call arriving at the specific trunk line 7, a central controller 6 controls a channel switch 9 to connect the specific line wire 7 to a PB signal receiver 2 and an answer message sending means 3, and sends out a message urging the dialing of the abbreviated dial number to the line wire 7 first. Then when the abbreviated dial number that the calling subscriber who receives the message dials reaches the specific line wire, it is sent to the central controller 6 through the PB receiver 2 and if there is a coincident abbreviated dial number among numbers registered in the central controller 6 previously, a dial signal corresponding to the telephone number of the opposite subscriber corresponding to the coincident abbreviated dial number is taken out of the central controller 6 and outputted to another line wire 8 to control the channel switch 9, thereby connecting the specific line wire 7 which is connected to the PB signal receiver 2 and answer message sending means 3 to the line wire 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a private electronic exchange having a speed dial service function.

BACKGROUND OF THE INVENTION Private electronic exchanges having speed dial service capabilities are generally known. However, these types of systems are only configured so that the speed dial service function can be utilized only when making a call using an extension telephone.

Problems to be Solved by the Invention Therefore, although this type of device is very convenient when making calls using an extension telephone, once you get used to it, it becomes difficult to make calls using a telephone other than an extension telephone, such as a public telephone. In this case, the user often forgets the other party's phone number and is unable to make a call, and there is a problem in that the user must always carry a notebook or the like with the phone number written down.

The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide an excellent electronic exchange that has a simple configuration and allows the use of speed dial service functions from telephones other than extension telephones. .

Means for Solving the Problems The present invention provides a method for sending a response message to the caller to dial a speed dial number when a call is received on a specific external line among a plurality of accommodated external lines. The means for sending the response message, and the caller's message to the above external line after sending this response message.
When a dial signal corresponding to the speed dial number arrives, in response, a dial signal corresponding to the telephone number of the other party corresponding to the speed dial number is sent to another outside line, and the other outside line and the specific outside line are sent. It is equipped with a means for connecting.

Therefore, according to the present invention, by simply dialing a specific external line among a plurality of accommodated external lines and dialing the speed dial number of the other party in accordance with the response message from the response message sending means, the other party at the speed dial number can be reached. Even if you forget the phone number of the other party, just knowing the specific outside line phone number and the speed dial number of the other party above will make it easier to call the other party than using a phone other than an extension phone. It has the function of being able to call and talk to the other party.

Embodiment The figure is a schematic configuration diagram of an embodiment of an electronic exchange according to the present invention, in which 1 is an extension telephone, 2 is a PB signal receiver, and 3
4 is a response message sending means, 4 is a terminal control line, 5 is a communication path control line, 6 is a central control unit, 7 is a specific outside line, 8 is another outside line, and 9 is a communication path switch.

In the above embodiment, if there is an incoming call on a specific outside line 7, this is detected by the central control unit 6. When the central control device 6 detects that there is an incoming call on a specific external line 7, the specific external line 7 is transmitted to the PB signal receiver 2,
The communication path switch 9 is commanded to connect to the response message sending means 3. Therefore, the communication path switch 9 connects the specific outside line 7 to the PB signal receiver 2 and response message sending means 3 according to the command. In this state, first, a response message such as "Please dial the speed dial number" is sent to the outside line 7. When the caller receives the response message and dials the speed dial number corresponding to the telephone number of the party he/she wishes to call, and the dial signal arrives at the above-mentioned specific outside line, it is received by the PB receiver 2 and centrally controlled. transmitted to device 6. When the central control device 6 receives the dial signal from the FB receiver 2, it is compared with a speed dial number registered in the central control device 6 in advance. If there is a match among the speed dial numbers pre-registered in the central control device 6, a dial signal corresponding to the telephone number of the other party corresponding to the matched speed dial number is extracted from the central control device 6. , which is output to another outside line 8. Then, the specific outside line 7 that has been connected to the PB signal receiver 2 and the response message sending means 3 is changed to the other outside line 8.
The communication path switch 9 is instructed to connect to the communication path switch 9. Therefore, in this state, if a specific outside line 7 is connected to another outside line 8 and the other party answers, it is possible to talk to the other party through the specific outside line 7 and another outside line 8.

In this manner, according to the above embodiment, by simply calling a specific outside line among the plurality of accommodated outside lines and dialing the speed dial number, the party assigned to the speed dial number can be called, and the other party's phone number can be called. This has the advantage that even if you forget the number, you can easily call the other party using a telephone other than an extension telephone.

In the above embodiment, a voice message such as "Please dial the speed dial number" is sent as the response message, but the response message may be a simple response sound.

Effects of the Invention As is clear from the above embodiments, the present invention is configured so that by calling a specific outside line and dialing a speed dial number, the destination of the speed dial number can be called. According to the present invention, it is possible to call and talk to the other party from any telephone simply by memorizing the speed dial number, and there is an advantage that there is no need to remember the telephone number of the other party each time.
